HAND-TOOL.

Specification of Letters Patent.

Patented Feb. 13, 191?.

Application filed December 7, 1915. Serial No. 65,620.

.To all whom it may concern:

Be it known that we, CARL G. HARRIS and JOHN A. ADELL, citizens of the United States, both residing at Orange, in the county of Franklin and State of Massa chusetts, have invented a new and useful Hand-Tool, of which the following is a specification. v v

This invention relates to a hand tool designed mainlyas a combined punch and eyelet set but adapted for use for other purposes. Y

The principal objects of the invention are to provide a simple and inexpensive device of this character which is not likely to get out of order and which can be made mainly by the cheap metal shaping operations, and also to provide a central anvil on opposite sides of which the cotiperating implements are mounted so as to provide a separate throat for each one; improved means for stripping the cardboard from the punch, and means whereby the same instrument can be used for jamming an eyelet after it has been set so as to remove it. Another object of the invention is to provide a construction in which the two tools as punch and eyelet set are separately located, and in which the throats for both shall be as deep as possible.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which,

-Figure 1 is a side view of a preferred form of instrument made in accordance with this invention, with parts in section, and shown in open position;

Fig. 2 is a sectional view on the line 2 2- of Fig. 1;

Fig. 8 is a perspective view of a portion of the device showing its operation in punch- 6 and 7 showing the work after it has been operated upon.

In the form shown the instrument is composed mainly of two members 10 and 11 formed of sheet metal and capable of being shaped up in dies in a very inexpensive manner. These are pivoted together at 13 and provided with a spring 12 which has its ends caught into the handles by indenting the latter at the points 14. In this way the spring normally tends to hold the'device open and'is not likely to get out of position when in use.

The handle members 10 and 11 are provided with two jaws 15 and 16 respectively. Each of these jaws is lJ-shaped in cross section and therefore strong and the jaw 15 in the first figure is provided with a die or hole 19 extending therethrough. Behind the face of the jaw 16 is a strong spring 20 riveted in position and provided with a pilot pin 21 fixed thereon; and the front wall of the jaw 16 is pierced by a hole which has a chamfered inner edge 22. The pin 21 passes through this hole. Passing through slightly elongated holes 23 in the two jaws is a guide pin 24:. Between the jaws is located an anvil 25. This is provided with a bifurcated end which straddles the pivot pin 13 by which the two jaws are pivoted together. It will be noticed that the bifurcated end of the anvil is thin enough so as to'permit it to pass in between the jaws and fit their walls so as to be held and guided by them. This anvil is fixed to the pin 2 1 and its movements are controlled thereby. It is provided at its outer end with a punch 26 and with a rivet set 27 of any desired type, located on opposite sides of it. Therefore it itself constitutes a central jaw cotiperating with each of the jaws 15 and 16.

A stripper 28 is shown which is fixed to the lower jaw at 29 by a swaging process and is provided with an upwardly extending curved end 30 adj aoent to the punch. It has a bifurcated end which terminates at the punch so as not to be in the way.

The projecting sharp edges or corners 31, four of which are shown, are designed for the purpose of permitting the operator to jam or destroy an eyelet after it has been set so as to provide for removing it. This is indicated in Fig. 4.

We have shown slight humps or stops 32 on the handles to assist the operator to keep his hand as far from the pivot as possible in order to insure a good leverage. The hollow handle is also utilized to form a magazine for eyelets by providing a closing plate 34 an end plate 35 and a pivoted cover 36.

Starting with the parts in the position shown in Fig. l as the jaws are closed together, the central anvil which was before in a retracted position is forced out centrally. This provides proper alinement of the parts and also permits the operator to place his paper or cardboard in the proper position on the jaws which he can see better than he could if the punch and set were in alinement with the hole and pilot pin respectively. As the jaws close the parts come together and hold the anvil firmly between them at the instant that the paper or cardboard. is punched or the eyelet set. On account of the construction the punch and eyelet set operate separately and a deep throat is provided for each.

On the motion back into normal position the stripper 28 strips the cardboard from the punch as the jaw 15 separates from it. It will be noted that the only motion of the anvil 25 is out and in and that the entire closing motion of the two cooperating jaws of each pair is performed by one of them, thus also further assisting the operator in placing the paper or eyelet in proper position and keeping it there before operating the device.

In the form shown in the last three figures different tools are used. In this case a central projection 4-0 registers with a previously punched article and a concentric semicircular cutter 41 cuts the end to the form shown in Fig. 8 at 42. A pair of creasing dies 43 and 44 are shown, the former being curved upwardly at one end to allow progressive creasing. These tools are intended for use mainly in a certain type of toy. The form shown in the other figures is useful for this purpose and also for commercial purposes.

Although we have illustrated and described only two embodiments of the invention, we are aware of the fact that many modifications can be made therein by any person skilled in the art without departing from the spirit and scope of the invention as expressed in the claims. Therefore, we do not wish to be limited to all the details of construction herein shown and described, but what we do claim is 1. In an implement of the class described,

the combination of two jaws, one having a die therein and the other having a pilot pin and a member located centrally between said jaws and provided with a punch on one'side for cooperating with the said die and with a rivet set on the other side for cooperating with said pilot pin.

2. In an implement of the class described, the combination of two jaws, one having a die therein and the other having a. pilot pin and an anvil located between said jaws and provided with a punch on one side for cooperating with the said die and with a rivet set on the other side for cooperating with said pliot pin, said anvil being maintained substantially in central position when said jaws are together.

3. In a hand tool, the combination of two jaws pivoted together, an anvil located substantially half way between them, each jaw and both sides of said anvil having tools thereon, and a pin fixed to said anvil and projecting therefrom into the respective jaws for holding the anvil in position, said anvil being bifurcated at its inner end and having the bifurcation extending over the pivot on which said jaws are pivoted together.
